Does this sound like the set of challenges you might be facing?

• Every lesson restarts with the same foundational stuff I already know cold "so everyone’s on the same page," and sitting through the re-explanation actually scrambles me
• Something just happened
• After one unusually bad showing I conclude something’s really wrong, and after one great one I’m sure they’ve turned a corner
• I had one unusually bad stretch, then I changed something, and now things are better
• There are so many options on the table that I’ve stopped weighing each one and started just grabbing for whatever looks easiest to compare

Practices that may help

1. Remove explanations the learner has already internalized
   Stop explaining what an expert already knows — redundant information adds cognitive load, not value.

2. The Decoy Effect — How an Irrelevant Option Changes Your Choice
   The decoy effect, documented by Huber, Payne and Puto (1982), is the finding that adding a third option that is clearly inferior to one of two existing options (but not the other) reliably shifts preference toward the option it is "dominated by." It shows that preferences between options are not fixed: they are constructed in context, and the comparison set shapes the outcome.
3. The Expertise Reversal Effect: When Help Becomes Harmful
   The expertise reversal effect, identified by Fred Paas, John Sweller, and colleagues, is the finding that instructional supports helpful for novices — worked examples, detailed guidance, redundant explanations — become ineffective or actively harmful as expertise grows. The mechanism is cognitive load: supports that reduce extraneous load for novices add extraneous load for experts who have already automated the relevant processes.
4. Correct for the recency amplification of availability
   Recent events feel more probable than they are — apply an explicit recency discount.

5. The Overjustification Effect: When Rewards Kill Motivation
   The overjustification effect is the finding that offering expected, tangible rewards for activities people already enjoy can undermine their subsequent interest in those activities once the reward is removed. Lepper, Greene, and Nisbett demonstrated this in children in 1973; later meta-analyses confirmed the effect is real for specific reward types, though the strong version of the claim — that any reward harms any intrinsic motivation — is overstated.
6. The Testing Effect: Why Retrieval Practice Beats Restudying
   The testing effect (also called the retrieval practice effect) is one of the most replicated findings in memory research: retrieving information from memory — through testing, quizzing, or free recall — produces stronger and more durable retention than spending the same time restudying the material. Roediger and Karpicke’s (2006) experiments showed that a test-only group outperformed a restudy-only group by a large margin on a one-week delayed test.
7. The Habit Discontinuity Effect
   The habit discontinuity effect, studied by Phillippa Lally and Bas Verplanken among others, shows that environmental disruptions — moving house, changing jobs, starting university — weaken the contextual cues that sustain existing habits, creating a window of increased behavior malleability. Evidence comes primarily from observational and survey studies; the effect appears real but its magnitude varies considerably by habit type and individual.
8. Expect extreme results to regress toward average
   Unusually good or bad performance predicts more average performance next time — account for this before giving praise or blame.
   The Representativeness Heuristic — Judging by Resemblance
9. Expect regression to the mean in extreme outcomes
   Unusually good or bad performance tends to be followed by more average performance — not because of what you did.

10. Simplify complex choices to prevent comparison fatigue from enabling decoys
    Too many options increase susceptibility to decoys — constrain the comparison set before evaluating.
